Brake Repair in Lac La Biche, AB
If you’re hearing grinding, experiencing poor stopping performance, or seeing warning lights, your brakes may need attention. At Ethos Mechanical, we provide thorough and efficient brake repairs for all heavy-duty, medium-duty, and light-duty vehicles. These repairs include:
- Brake Shoe & Pad Replacement – Brake shoes and pads generate the friction needed to bring your truck to a stop. Worn or uneven shoes reduce stopping power and put your truck at risk.
- Slack Adjuster Replacement – Slack adjusters maintain proper brake shoe distance as parts wear down. Faulty adjusters can lead to delayed or uneven braking.
- Brake Drum & Disc Replacement – Brake drums and discs house your brake shoes and suffer from heat and wear over time. Damaged drums compromise safety and need immediate replacement.
- S-Cam Replacement – The S-cam rotates to engage the brake shoes. A worn cam can prevent full brake activation and lead to reduced braking efficiency.
- Brake Chamber Replacement – This component converts compressed air into braking force. A malfunctioning chamber results in lagging or unresponsive brakes.
